When the phone is located at greater distances from
the user, the exposure to RF is drastically lower because
a person’s RF exposure decreases rapidly with
increasing distance from the source. The so-called
“cordless phones,” which have a base unit connected to
the telephone wiring in a house, typically operate at far
lower power levels, and thus produce RF exposures well
within the FCC’s compliance limits.
2. Do wireless phones pose a health hazard?
The available scientific evidence does not show that any
health problems are associated with using wireless
phones. There is no proof, however, that wireless
phones are absolutely safe. Wireless phones emit low
levels of radio frequency energy (RF) in the microwave
range while being used. They also emit very low levels
of RF when in the stand-by mode. Whereas high levels
of RF can produce health effects (by heating tissue),
exposure to low level RF that does not produce heating
effects causes no known adverse health effects. Many
studies of low level RF exposures have not found any
biological effects. Some studies have suggested that
some biological effects may occur, but such findings
have not been confirmed by additional research.
In some cases, other researchers have had difficulty in
reproducing those studies, or in determining the
reasons for inconsistent results.
3. What is FDA’s role concerning the safety of wireless
phones?
Under the law, FDA does not review the safety of
radiation emitting consumer products such as wireless
phones before they can be sold, as it does with new
drugs or medical devices. However, the agency has
authority to take action if wireless phones are shown to
emit radio frequency energy (RF) at a level that is
hazardous to the user.
In such a case, FDA could require the manufacturers of
wireless phones to notify users of the health hazard and
to repair, replace or recall the phones so that the hazard
no longer exists.
Although the existing scientific data do not justify FDA
regulatory actions, FDA has urged the wireless phone
industry to take a number of steps, including the
following:
• Support needed research into possible biological
effects of RF of the type emitted by wireless phones;
